txtファイルをアップロードするだけでAndroidAPI15でシンプルなアプリを構築するために、developers.google.comでDrivev2に関するすべての情報をフォローしています。ライブラリの正しいJavaビルドパス（私の場合は1.11.0）のように、その周りで何時間も費やした後、ドライブSDK、クライアントIDのAPIアクセスなどを有効にしてセットアップします。この投稿で良い例を見つけましたGoogleドライブがAndroidアプリにエラー400または403を返しますか？ここで、アプリで使用しているのと同じエラーの説明を見つけました。これは私の完全なコードです（他の人に役立つことを願っています）：
public class DrivexampleActivity extends Activity {
Context activity = null;
boolean alreadyTriedAgain;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AccountManager am = AccountManager.get(this);
activity = this.getApplicationContext();
Bundle options = new Bundle();
Account[] acc = am.getAccounts();
am.getAuthToken(
(am.getAccounts())[8], // #8 just in my phone case. you can debugg the acc variable to find your @gmail account index.
"oauth2:" + DriveScopes.DRIVE,
options,
true,
new OnTokenAcquired(),
null);
}
private class OnTokenAcquired implements AccountManagerCallback<Bundle> {
@Override
public void run(AccountManagerFuture<Bundle> result) {
try {
final String token = result.getResult().getString(AccountManager.KEY_AUTHTOKEN);
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
Drive.Builder b = new Drive.Builder(httpTransport, jsonFactory, null);
b.setJsonHttpRequestInitializer(new JsonHttpRequestInitializer() {
@Override
public void initialize(JsonHttpRequest request) throws IOException {
// TODO Auto-generated method stub
DriveRequest driveRequest = (DriveRequest) request;
driveRequest.setPrettyPrint(true);
driveRequest.setKey("xxxxxxxxxxxx.apps.googleusercontent.com"); // I replaced the number with x's. for your Client ID from Google API Console
driveRequest.setOauthToken(token);
}
});
final Drive drive = b.build();
final com.google.api.services.drive.model.File body = new com.google.api.services.drive.model.File();
body.setTitle("My Test File");
body.setDescription("A Test File");
body.setMimeType("text/plain");
java.io.File fileContent = new java.io.File("document.txt");
final FileContent mediaContent = new FileContent("text/plain",fileContent);
new Thread(new Runnable() {
public void run() {
com.google.api.services.drive.model.File file;
try {
file = drive.files().insert(body, mediaContent).execute();
Log.i("Hi", "File ID: " + file.getId());
alreadyTriedAgain = false; // Global boolean to make sure you don't repeatedly try too many times when the server is down or your code is faulty... they'll block requests until the next day if you make 10 bad requests, I found.
} catch (IOException e) {
if(!alreadyTriedAgain){
alreadyTriedAgain = true;
Log.i("Hi", "The upload/insert was caught, which suggests it wasn't successful...");
e.printStackTrace();
}
}
}
}).start();
Intent launch = null;
launch = (Intent)result.getResult().get(AccountManager.KEY_INTENT);
if (launch != null) {
Log.i("Hi", "Something came back as a KEY_INTENT");
startActivityForResult(launch, 3025);
return;
}
} catch (OperationCanceledException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (AuthenticatorException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 3025) {
switch (resultCode) {
case RESULT_OK:
AccountManager am = AccountManager.get(activity);
Bundle options = new Bundle();
am.getAuthToken(
(am.getAccounts())[8], // #8 just in my phone case. you can debugg the acc variable to find your @gmail account index.
"oauth2:" + DriveScopes.DRIVE,
options,
true,
new OnTokenAcquired(),
null);
break;
case RESULT_CANCELED:
// This probably means the user refused to log in. Explain to them why they need to log in.
break;
default:
// This isn't expected... maybe just log whatever code was returned.
break;
}
} else {
// Your application has other intents that it fires off besides the one for Drive's log in if it ever reaches this spot. Handle it here however you'd like.
}
}
またマニフェスト：

ただし、常に次のエラーが発生します。
com.google.api.client.http.HttpResponseException: 400 Bad Request
{
"error": {
"errors": [
{
"domain": "usageLimits",
"reason": "keyInvalid",
"message": "Bad Request"
}
],
"code": 400,
"message": "Bad Request"
}
}
私の場合、DRIVESDKとDriveAPIにエラーはないようです。なにか提案を？？お願いします！！
